SPECIFICATION forming part of Letters Patent No. 654,136, dated Ju1y` 24,.19oo.

Application tied April zo, 1897.

To @ZZ whom, it mttg/concern: l Be it known that I, ARTHUR B. COWLES, of Rochester, in the county of Monroe, in the State of New York, have invented new and usefullmprovementsinPaper-BoXMachines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in 1o machines particularly applicable for making the exteriors or shells of sliding boxes, as cigarette-boxes, and has for its object the production of'a machine for the desired purpose, which operates with great rapidity, is particularly simple in construction, 'and is highly efficient in use; and to this end the invention consists in the combination, construction, and arrangement of the component parts of a paper-box machine, all as hereinzo after fully described, and pointed out in the claims.

In describing this invention reference is had to the accompanying drawings, forming a part of this specification, in which like letters indicate corresponding parts in all the views. y

Figures 1 and 2 are respectively side elebox machine. Figs. 3 and 4 are vertical sec- 3o tions taken, respectively, on lines 33V and 4 4, Fig. 2. Fig. 5 is a top plan view, partly broken away, of a portion of the front end of my improved paper-box machine,'showing the upper cutting and scoring roller, the formers and bending means adjacent to said roller, and a pair of blanks operatively engaged by said formers and bending means. Fig. Gis a top plan view, partly broken away, ot' a portion of the central or intermediate part of 4o said paper-box machine, showing the rear formers and bending means and apairof blanks operatively engaged by said formers and bending means.' Figs. 7, 8, 9, 10, 11, 12, and 13 are vertical sections, partlyI in elevatiom'taken, respectively, on lines 7 7, 8 s,.e 9, 10 10,11 11, 12 12, and 13 13, Fig. 1. Fig. 14 is an enlarged vertical section, partly in elevation, of portions of the cutting and scoring rollers of my improved 5o paper-box machine. Figs. 15 and 16 are iso- Serial No. 632,906. (No model.)

metric views of lthe detached front and rear formers of myimproved machine, Fig. 17 is an isometric view of the tie-piece for the lengthwise bars or divisions of the rear former. Fig. 18 is an isometric view of the gagement with the glue-applying wheel and the clamp orholder for securing said presserpiece in position. Fig.. 19 is an isometric view of one of the detached lengthwise bars arranged at the side 4oi the rear former for supporting the bending "means cooperating with said former, a portion of one of the crosswise bars-upon which said lengthwise bar is mounted being also illustrated. Fig. 2O is a vertical section taken on line 2O 20, Fig. 13. Fig. 21 is an enlargeds'ection of one of the detached presser-pieces for hammering or pressing together the glued portions of the blanks. Figs. 22, 23, 24, 25, 26, 27, and 2S are isometric views of one of the blanks, partly broken away, fed through my improved machine and formed thereby into a tubular shell, these views showing the various manipulations of the blank; 4and Fig. 29 is an isometric view of a portion'of one of said shells bent into its usual form.

The main frame A of my improved paperbox machine may be of any desirable form, size, and construction and is usually provided at its front end with suitablecutting and scoring rollers B B' and a support a, which is arranged at one side of the rollers B B and supports the blanks or other articles fed to said rollers. These blanks or other articles are arranged between guide-rails or gages ct a2, mounted upon the support a.. of the guide-rails or gages, as the one a2, is generally .adjustable automatically toward and away from the other guide-rail orgage and is preferably guided in its ,movement by 1 arms O53, which proj ect laterally fromjitsouter v face. 0.4, rising from the mainframe A, and are en- The armso.3 are movable in bearings circled by springs a5, which yieldingly force the guide-rail or gage a2 toward the opposite guide-rail or gage a. The ends of the guiderails or gages a a2 usually support a guideroller a6, arranged in close proXimity'to the 'cutting and scoring rollers B B and having i presser-piece for forcing the blanks into en" One ,. or gages.

its opposite ends formed with trunnions journaled in the adjacent ends'of said guide-rails As best seen at Fig. 2, the trunnion of the roller 0,6, journaled in the guiderail or gage a2, is of considerable length in order to obviate disengagement of said trunnion from the guide-rail or gage a2.

The cutting and scoring rollers B B' may be of any suitable form, size, and construction and are preferably arranged one above the other. The lower roller B is usually journaled in xed bearings provided upon the main frame A and is preferably driven positively by gearing B2, Fig. 2, which connects the shaft of said roller to an adjacent shaft d, presently described. The upper roller B is generally driven frictionally by engagement with the blanks or other articlespassed between the rollersB B' and is supported in bearings provided upon one extremity of a movable frame A', having its opposite extremity iiexibly connected by pivots a7 to the main frame A. Asuitable adjuster a8 is engaged with the free extremity of the movable frame A' for varying the position of said movable frame and forcing the roller B' and a feed presently described toward the roller B and the blanks or other articles engaged by said rollers B B'. The adjuster d8 is usually supported in a bracket a, rising from the frame A, and as the movable frame A' is generally composed of substantially-parallel bars arranged on opposite sides of the path of movement of the blanks or other articles, as best seen at Fig. 2, I preferably use two adj usters as and two brackets a2 for supporting said adjusters. I generally limit the down- Ward movement of the free end of the frame A' by a suitable longitudinally-adjustable stop am, Fig. 1,Which is secured to the main frame A. The movable frame A' forms a particularly practical and effective means for supporting the roller B'; but it is obvious that any other suitable frame may be used for this purpose, if desired.

Each of the rollers B B' is usually provided with a cutting-knife b, and these cuttingknives are arranged to split lengthwise a blank or other article fed to the rollers B B', and thus form two blanks c c, Fig. 5, arranged side by side, in order that two box exteriors or shells may be made side by side at the same time by my improved machine. If, however, the blanks or other articles are first cut to the desired width,no cutting-knives b upon the rollers B B are necessary. The scoring-knives b' of the rollers B B are preferably provided upon the lower roller B and enter annular grooves b2 in the upper roller B'. Said' scoring-knives are generally arranged so as tov provide the blanks or other` articles c with lengthwise scores or creases c c2 c3 c4, which divide said blanks into length- Wise portions c5 c6 o7 c8 o9, as best seen at Figs. 22 and 25. The lengthwise portions c6 o8 of the blanks c are of substantially the same width as each other and are of less Width than the lengthwise portions c5 c7, which are also of substantially the same width as each other. In the operation of my improved machine, as will be hereinafter described, the outer portions of the blanks c are bent upwardly from the creases or scores c' c2 c2 c4, glue is applied to the lengthwise portions o9, and said lengthwise portions a9 are folded beneath the outer parts ofthelengthwise portions c5.' It is obvious, however, that the blanks c may be provided with a greater or'less number of lengthwise scores or creases and may be otherwise operated upon by my improved machine, if desired.

The blanks c fed between the rollers B B' are engaged by a suitable feed extending lengthwise of the main frame A from a point in close proximity to said rollers. This feed may be of any desirable form, size, or construction and usually consists of endless belts D, having their front ends passed over pulleys CZ' on the shaft d, previously mentioned, and their opposite ends passed over a drum d2, suitably connected to a driving-shaft D. The upper and lower portions of the belts D D, interposed between the pulleys d' and the drum d2, are respectively supported by upper and lower idlers d2 d4. The upper portions of the belts D engage only the lower faces of the blanks or other articles fed from the roll- A ers B B', and consequently I preferably provide my improved machine with suitable addi-` tional feeds, which en gage the upper faces of IOO said blanks or other articles and usually con- I j are journaled in yielding bearings supported by the movable frame A', and the belts D3 are passed over pulleys d, journaled in yielding bearings supported by a movable frame A2, arranged at the rear of the frame A'. 'Ihe movable frame A2 preferably consists of parallel bars arranged at opposite sides of the path of movement of the blanks or other articles fed through my improved paper-box machine. The rear ends of said bars are usually iiexibly connected to the main frame A by pivots all, and their front ends are forced toward the belts D and the blanks or other articles c by suitable adj usters @12, which are preferably mounted in brackets @12, rising from the frame A. Suitable stops 0,14, similar to the stops am, previously described, are generally utilized to limit the downward movement of the free end of the frame A2. The described means for feeding the blanks or other articles c is particularly practical and effective; but other suitable devices may be used for this purpose, if desired. During the engagement of the blanks or other articles c by the belts D D2 D3 suitable meansU IIO' Each of the formers E, as best seen at Figs. 2, 5, and 15, is arranged in close proximity to the cutting and scorin g rollers B B', and preferably consists of lengthwise bars or divisions e @,arranged side by side and adjustable laterally toward and away from each other. The front extremities of the inner or adjacent portions of the bars e e are generally provided with longitudinal cut outs d, which form lengthwise slots in the formers E, and the outer side edges of said bars e are usually formed with diverging portions e2. The front said frames.

and rear ends of the bars e e are provided with upwardly-projecting arms e3 e4, secured, respectively, by suitable fastening means to the shaft d7for one of the pulleys d5 and to a transverse rod or bar ali. The shaft @Z7 and the rod or bar als are generally supported by the front or free ends of the movable frames A A2, and consequently the formers E are secured to The adjusters as L12 thus operate to vary the position of the formers E. The cut-outs e' in the formers E receive the belts D2 and permit said belts to engage the blanks or other articles passed beneath said formers.

The means for bending the blanks or other articles c at their lengthwise scores or creases c2 c4 and folding said blanks or other articles upon the form ers E preferably consists of rollers ff fgf, which are arranged at the outer side edges of the bars or divisions e e in advance of the diverging portions e2 thereof. The rollers ff f2f3 are usually formed with engaging surfaces, which are arranged at different angles to the side edges of the formers E, and a number of said rollers are supported at the rear of the belts D2. Some of the rollers fff2f3 bend the outer portions of the blanks c upwardly from the scores or creases c2 c4 at opposite sides of the belts D2, as best seen at Figs. 8 and 23, and others of said rollers fold the upwardly-bent portions of the blanks upon the formers E at the rear of the belts D2, as best seen in Figs. 5, 9, and 24. The rearwardly-diverging portions e2 of the outer side edges of the formers E then reversely bend the outer side portions of said blanks, as best seen at Figs. l0 and 25. The rollers ff'f2f3 are preferably journaled in yielding arms or portions of suitable suports secured to bars F, adjustable laterally toward and away from the longitudinal edges of the formers E. The bars F are generally provided with depending eyes,which are movable lengthwise of bars f4, extending crosswise of the belts D, and are secured in position by suitable set-screws engaged with said bars f4.

The formers E', Figs. 2, 4, and 16, are supported at the rear of the formers E and are usually so arranged that their engaging or outer side edges are out of alinement with the similar edges of the formers E in order to facilitate the bending of the blanks or other articles c at the scores or creases c' c3, as best seen at Fig. 26. Each of the formers E preferably consists of substantially parallel lengthwise bars or divisions e5 e5, adjustable laterally toward and away from each other, and the front ends of the inner portions or edges of the bars or divisions e5 e5 are generally provided with longitudinal cut-outs e6, which formlengthwise slots in the formers E for receiving the belts D3 and permitting engagement of said belts with the blanks or other articles passed beneath the formers E. The top faces of the rear ends of said bars or divisions e5 e5 usually incline upwardly from their outer side edges, and the rear extremities of said inclined top faces incline downwardly toward the belts D. The front ends of the formersE are provided with upwardlyextending arms e7, which are adjustable length wise upon a transverse rod o16, provided upon the movable frame A2. The arms e7 are usually formed with crosswise slots es, which receive suitable fastening means, as screws e?, for securing the front extremities of the bars or divisions e5 e5 to said arms e7 and permitting the lateral adjustment of the front ends of said bars or divisions toward and away from each other.

ject into the cut-outs e6 in the inner or adjacent edges of the bars or divisions e5 e5. These rollerse10 are preferably secured to the arms length for separating said bars any desiredv distance. i

The means for elevating the portions of the blanks or other articles extending outwardly beyond the scores or creases c c3 and folding said portions of the blanks upon the formers E/ preferably consist ot belts f5, rollers f6, and presser-pieces f7f8. The belts f5, Figs. 1, 2, and 1l, are usually passed over pulleys fg, mounted on the shafts d8 d8, for two of the idlers'cZS. The upper portions of said belts extend upwardly above the belts D in the paths of movement of the outer portions of the blanks o, and thus bend upwardly said outer portions, Fig. 11, and facilitate the onward feeding of the blanks c. The rollers f6 are arranged at the rear of the belts fand are provided with engaging faces arranged at different angles to the engaging or longitudinal outer edges of the formers E', and the engaging faces of the rear rollers f6 are arranged at gradually-decreasing angles to the upper faces and the outer side edges of said formers for gradually folding the blanks upon the formers E, as best seen at Figs. 6, l2, 13, and 27. Said rollers]c6 are usuallyjournaled -in yielding arms or portions of suitable supports secured to bars f1, Figs. 2 and 19, ad-

The arms e7 gen-v` erally support presser-rollers ew, which pro- IIO justable laterally toward and away from the outer side edges of the formers E. The front ends of the bars f1 are provided with eyes movable lengthwise of a shaft d1 for one of the idlers d3, and the rear ends of said bars are adjustably secured to a bar a1?, extending crosswise of the belts D.

The presser-pieces]L17 preferably consist of endless belts arranged in alinement with the formers E above the belts D and extending rearwardly beyond said formers. The opposite ends of the belts forming the presserpieces f7 are usually passed over pulleys f11 f12, arranged onevin advance of the other and supported,respectively, by the movable frame A2 and armsvprojecting upwardly from the main frame A. The lower faces of the pulleys f11 are generally arranged in close proximity to the belts D, and the corresponding faces of the pulleys f12 are considerably elevated above said belts. Suitable idlers f13 are arranged at the rear of the pulleys )012 above the lower portions of the belts forming the presser-pieces f7. The lower faces of the idlers f13 are supported in close proximity to the belts D, and consequently the front ends of the lower portions of the belts forming the presser-piecesf7 incline downwardly from the pulleys f12 tothe idlers f 13 and the belts D and operate to gradually flatten the blanks or other articles folded, as in Fig. 6, by the rollers f6. As presently described, glue or paste is applied to the lengthwise portions e9 of the blanks or other articles c before their engagement by the presser-pieces f7, and therefore by gradually flattening said blanks the glued surfaces thereof are caused to assume their proper position for forming folded blanks of uniform width. The presser-piecef8 usually consists of a roller extending crosswise of the belts D at the rear of the presser-pieces f7 and having its extremities journaled in arms projecting upwardly from the frame A. The presser-piece f8 may, however, be dispensed with, if desired.

Before the blanks or other articles c are fed beneath the formers E a feed of any desirable construction operates to apply a suitable amount of glue or paste to the lengthwise portions c9 of said blanks. The means for feeding said glue or paste preferably consists of wheels g, Figs. 4E and l0, which are mounted upon a shaft d10 for one of the rollers d3 and engage the under surfaces of said portions ci. Suitable presser-pieces g force the blanks c into engagement with'the glueapplying wheels g in order to insure positive feeding of the glue. may beof any desirable construction, but preferably consist of spring-arms secured to supporting clamps or holders which usually consist of split eyes g2, adjustable lengthwise of a rod or bar 0,18, extending crosswise of the belts D. The split eyes g2 are generally secured in position by screws or other fastening means g3. The wheels g revolve in a glue-containing receptacle G, which is pref- These presser pieces.

l erably mounted on a movable frame A3 and is supplied with glue or paste by apipe g4, depending from a superimposed glue-containing receptacle g5. The pipe g1 is provided with a valve Q6, which is operated by a handpiece gl, Fig. 10. A suitable'steam-pipe g8, Fig. l, enters the upper glue-containing receptacle g5 and maintains the desired temperature thereof. The support A3 for the gluecontaining receptacle G is preferably movable lengthwise of revoluble screws gi), which are connected by bevel-gears Q10 to a shaft g11, provided with a handpiece Q12. The means for folding the blanks or other articles and applying glue or paste thereto are particularly practical and effective; but, if desired, any other suitable devices for performing these operations may be embodied in my improved machine..

In the preferable construction of my paperbox machine I use a blower H for facilitating the cooling and drying of the glue or paste applied to the blanks or other articles c. This blower may be of any desirable form, size, and construction and is here shown, Figs. l and 13, as composed of an upright tube provided With'diverging ends h h, arranged in advance of the presser-piece f7 in close proximity to the rollers f1. The blower I-I is connected to any suitable fan or other device for creating a circulation therein and is preferably supported by a rod am, which extends crosswise of the movable frame A2 and is detachably ,secured to said frame by any desirable fasteningmeans. As usuallyconstructed the blower H is provided with an eye h', Figs. l and 2O,` which ismovable lengthwise of said rod C119. The blower H by facilitating the cooling and drying of the glue applied to the blanks c greatly increases the etliciency and rapidity of operation of my improved paper-box machine and is therefore a feature of considerable advantage. Itis obvious, however, that said blower may be dispensed with, if desired.

After the blanks or other articles c are folded, as described, they are then squeezed or subjected to pressure by any suitable means in order to insure proper adhesion of their glued or pasted surfaces. The means for squeezing the blanks may be of any desirable form, size, and construction, but preferably consists of presser-rollers d d12, belts Z13 d, and presser-pieces 111. The presser-rollers C211 are mounted in yielding bearings and are arranged one in advance of the other crosswise of the drum d2. The presser-rollers i12 are arranged between the idlers d4 d1 above and below theinterposed portions of the belts D C113 d13, and the upper presser-rollers i12 are usually mounted in yielding bearings. The belts Z13 Z13 are passed around the presserroller (111 nearest the presser-pieces f7 f8, are extended downwardly and upwardly on opposite sides of the remaining presser-rollers d, and are then continued forwardly beneath the lower portions of the belts D D and IOS IIO

IIS

around the idlers d4 d4. The presser-pieces 114 preferably consist of revoluble toothed wheels, which are mounted in yielding bearings and operate to intermittently press or hammer the folded blanks interposed between the belts D Z13 (Z13. Said presser-pieces d are usually raised intermittently out of operative position by suitable means, as toothed Wheels d, mounted upon the shafts for the idlers d4 d4 and engaged with rollers upon the ends of said presser-pieces. Afterthe blanks are squeezed or subjected to pressure, as described, they are discharged from between the belts D (Z13 Z13 into a receptacle (not illustrated) and are then cutinto suitable lengths, as shown in Fig. 29. The means for squeezing or exerting pressure upon the blanks c is particularly applicable for use in connection with the remaining parts of myimproved paper-box machine; but any other suitable means may be used for this purpose.

The construction of my improved paperbox machine will now be readily understood upon reference tothe foregoing description and the accompanying drawings. In the operation of said machine the blanks are placed upon the support a, between the guide-rails or gages a a2, and are fed between the cutting and scoring rollers B B', which divide said'blanks into lengthwise blanks c and provide the blanks c with lengthwise scores or creases c' c2 c3 c4. The blanks c arepassed beneath the formers E and are engagedby the rollers fff2f3, which bend the outer portions of said blanks upwardly from the scores or creases c2 c4 and fold the same upon the front ends of the formers E. The diverging portions of the outer side edges of the formers E depress the u pwardly-folded portions of the blanks c, and glue or paste is then applied to the lengthwise portions o9 of said blanks, whereupon the blanks are passed beneath the formers E. The belts]5 and the rollers f6 bend the outer portions of the blanks c upwardly from the scores or creases c c3 and fold the same upon the formers E'. .The blower H cools and partially dries the glue applied to the blanks c, and the presser-pieces f7f8additionally fold or Hatten the blanks c, whereupon said blanks are squeezed between the drum cl2, presser-rollers d dlg, idlers d4, and presser pieces C114 and are discharged from the machine.

It is obvious7 as previously indicated, that the exact detail construction and arrangement of the component parts of my improved paper-box machine may be considerably varied without departing from the spirit of my invention, and hence I do not herein specifically limit myself to such exact detail construction and arrangement.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
